More generally, I work mostly in the philosophy of physics, which heavily intrudes into metaphysics and general philosophy of science. Specifically, I work on space and time, time travel, persistence, identity, laws of nature, determinism, and causation.

Out of Nowhere: The Emergence of Spacetime in Quantum Theories of Gravity

I am currently writing a book with Nick Huggett, which is under contract with Oxford University Press. It starts out from the recognition that in quantum theories of gravity, spacetime disappears in some sense or other and investigates the philosophical implications of a fundamentally non-spatiotemporal world, as well as how spacetime is thought to re-emerge in various of the main approaches to quantum gravity.
